Kinda makes you worried about the stability of the DNS system if someone so small on the "food chain" can create such instablility. ------------------------------------------------------------------------ ------------------------ Jesse W.

<<File: ATT16935.ATT>> This has been corrected temporarily. With brute force ;-)

Genieweb is a downstream customer of Los Nettos, one of our customers. No-one has been able to reach the company or the contact, so their T1 was just taken down. I expect a call rather soon, so we can get them to fix their mistake.

But it does bring up an interesting point.... is it that easy to create chaos? They are so far down the food chain, and yet....

com. 304 SOA genieweb.com. root.genieweb.com. ( 11 ; serial 10800 ; refresh (3 hours) 3600 ; retry (1 hour) 604800 ; expire (7 days)

This was cached on one our name servers. Sure enough, dig any com @genieweb.com shows:

;; ANSWERS: com. 86400 SOA genieweb.com. root.genieweb.com. ( 11 ; serial 10800 ; refresh (3 hours) 3600 ; retry (1 hour) 604800 ; expire (7 days) 86400 ) ; minimum (1 day) com. 86400 NS genieweb.com.

;; AUTHORITY RECORDS: com. 86400 NS genieweb.com.

;; ADDITIONAL RECORDS: genieweb.com. 86400 A 198.147.97.23

I wonder if this is what has been causing random COM domain lookups to fail for random people at random places.

The time I can see this affecting a name server is if it does a lookup for a domain that's lamely delegated to genieweb.com, and then caches the 'com' reply.

I've already left voicemail for the genieweb people.
